china is one of the largest countries in the world in terms of planted forests area. Planted forests play an important role in soil and water conservation, food source, timber supply and energy security, but there are still many problems waiting for immediate resolution. Based on the current development status of planted forest in china, the paper made an comprehensive analysis for the positive impact and existing problems with regard to planted forests, and then came up with policy recommendations for promoting sustainable management of planted forests, mainly including: 1) to accelerate planted forests development and improve the quality; 2. to strengthen the protection and management, and quicken the development of planted forests; 3) to enhance the scientific planning for planted forests; 4) to reinforce the management for forests harvesting so as to promote the reasonable utilization of planted forests; 5) to perfect the management system for planted forest resources and improve the managerial capacity; 6) to complete related laws and regulations and improve the policy guarantee system; 7) to reinforce the forest tenure reform and establish a sound planted forest land transference system. Finally, the paper presented the future action framework for guiding the sustainable management of planted forests in china.

黄土高原黄土团粒组成及其与碳酸钙关系的研究

亚洲精细农业与计算机农业应用联合大会

作者： Baoguo Wu1 Yan Qi1,2.Chi Ma3 Hongquan Zhang4 (1.beijing forestry University beijing 100083 2.china Agricultural University, beijing 100083 3.beijing Park Service and Afforestation Bureau, beijing 10002. 4.forest inventory and planning Institute of Hebei Province 050051.)

The paper is based on the research of forestry experts’ systems funded by "National Tenth-Five-Year 863 Plan". In the context of the collective forest rights system reforms, in order to enhance the technological support to the farmers in the fast-growing and high-yield poplar cultivation and to satisfy the actual needs of related enterprises, the study focuses on the fast-growing and high-yield poplar plantation harvest model and related decision-making criteria. Taking Populus tomentosa Carr as an example, by adopting the age - diameter at breast height growth model, diameter and tree height model, and the dual volume model based on Hebei Province’s data, the age-volume produce model is constructed;by adopting market price of the non-discount method which is relatively easy for farmers, PNW （Present Net Worth） and Le （Land Expectation Value） calculation methods, the economic benefits evaluation model is established. By using the calculation results of these models as a decision-making benchmark, the growth model, evaluation model and an calculation example of Populus tomentosa Carr are obtained. Based on the above-mentioned studies, the components and functions, model base and model resolver algorithm of the system are designed, and the economic benefits forecast process is set. The results of the research is applied to the "National Eleventh-Five-Year Plan" funded program "The research and application of key technologies in fast-growing and high-yield plantation production and management process informatization ". And the application obtains a satisfied result. By using harvest evaluation system to conduct economic benefits analysis of poplar varieties, the farmers and the investors can predict future earnings, and to make decisions in reforestation.

通过团粒分析、电子显微镜 (SEM/EDX)扫描等元素分析扫描方法和手段 ,对黄土高原西北部自然黄土中的团粒数量及其与碳酸钙的溶解量的关系、团粒表面和内部碳酸钙的分布进行了研究。结果表明 :碳酸钙大约参与了 99%的团粒形成 ,呈现团粒越大 ,碳酸钙含量越多的趋势 ;反之 ,团粒数量与碳酸钙的溶解量成反比 ;随着团粒表面碳酸钙分布的减少 ,附着在团粒表面的微团粒及粉粒、粘粒减少 ;在团粒内部 ,碳酸钙与矿物颗粒之间存在 3种胶结方式 ,分别为碳酸钙附着在矿物颗粒表面、碳酸钙分布于矿物颗粒之间以及碳酸钙表面附着矿物颗粒。实验结果证明了黄土团粒的主要胶结物是碳酸钙这一理论。

Impact of the 2008 Ice Storm on China’s Forests

Reflections on Reinforcing administration over Protection of Historic and Cultural Heritage

2.11 International Symposium on Water Resource and Environmental Protection(ISWREP 2.11)

作者： Benzhi Zhou Mukui Yu Yonghui Cao Xiaoming Wang Honggang Sun Research Institute of Subtropical forestry Chinese Academy of forestry Fuyang Zhejiang {2.

An unprecedented ice storm occurred in south china in early 2.08, bringing extensive damages and huge losses to china’s {2.s. By site specific survey, coupled with review of the government documents and reports, we made an impact assessment of the ice storm on china’s {2.s at regional and local scale. The ice storm affected one-tenth of the {2.s in 19 provinces, with masson pine, Chinese fir and bamboo plantation among the most extensively slashed. The damage degree for the subtropical typical {2. types ranged from 2.% to 66%. Icedamage to tree/bamboo exhibited different patterns, with uprooting and bending being the most common. The topographical variables （altitude, slope aspect）, stand density, tree size and age, and management practice were all found to have effects on damage severity. High altitude and north-faced slope aggravated ice damage;native pine exhibited better resistance to damage than exotic. The effect of stand age and tree size on damage seemed to vary with species. The ice storm taught us valuable lessons. Native species should be put at the most priority in large scale {2.ation. Good management practice may help to reduce the risk of extreme climatic events. Sustainable extraction of non-timber goods is essential to planning for the risk of extreme events in {2. resources use.
